Comment 82 for bug 1521173

I too like Thorsten have a Ryzen workstation, and incidentally the same network chipset but a different motherboard (asrock ab350m pro4)

1f:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller

I think this error message is generic and different type of problems hides behind it, in my case every once in a while my PC slowly freeze, before freezing I see the AER error, after I have seen a lot of them it freeze.

adding "pcie_aspm=off" makes the error messages disappear and it freeze silently or it shows "r8169:rtl_counters_cond == 1" before freezing.
